Trouble with Cortex-M "Hello World"

[Jens Bauer via Digitalmars-d]

I got a little further, and will continue to look into the issue.
Currently, this is what I've gotten so far...

arm-none-eabi-gdc start.d -c -wrapper gdb,--args

break expression.c:11707
break expression.c:11570
break init.c:1015
break init.c:557
